SmartSealNatural Stone Sealer - Dry Finish – Impregnating, Durable Sealer for Sandstone, Limestone, Granite, Travertine and Slate (1 Litre)

Q: Can this be used as a sealant inside a birdbath. Other comments said outside.

It could be used inside, yes. but please remember this is a water repellent sealer, it is not formulated to be used as a waterproofing sealant. Hope that helps, George@Smartseal

Q: Is this suitable for kandla Indian sandstone? Does is prevent staining if not which of your products does? Thank you.

Yes, this is for Kandla Indian Sandstone, no sealer will claim to prevent staining, but this formulation is stain resistant. Hope that helps. Regards, George@Smartseal

Q: Is this suitable to seal old porous brick pavers on a patio? I want to stop lichen, moss algae growth.

Yes it is if you do not want to change the appearance. If they are very porous, you might have to reduce the m2 coverage per litre a bit. Samples are available. Hope that helps. George@Smartseal

Q: Is this suitable for marble or granite?

Yes it is, but due to the density of marble and granite use sparingly. I would suggest applying by cloth or sponge. Hope that helps!
